From f406041b58eadc716d6227408d3af553d566ffeb Mon Sep 17 00:00:00 2001 From: "Arnout Vandecappelle (Essensium/Mind)" <arnout@mind.be> Date: Tue, 4 Apr 2017 17:31:29 +0200 Subject: [PATCH] configure: try linking to detect stack-protector support Even if gcc accepts the -fstack-protector argument, it is possible that the libssp support library is missing. Detect this by linking instead of just compiling.
